LA Varistor Series
The LA Series of transient voltage surge suppressors are radial-lead
varistors (MOVs) that are designed to be operated continuously across
AC power lines. These UL recognized varistors require very little
mounting space, and are offered in various standard lead form options.
The LA Series varistors are available in four model sizes: 7mm, 10mm,
14mm and 20mm; and have a V
voltage range from 130V
M(AC)RMS
to 1000V, and an energy absorption capability up to 360J. Some LA
series model numbers are available with clamping voltage selections,
designated by a model number suffix of either A or B. The “A” selection is
the standard model; the “B” selection provides a lower clamping voltage.
See LA Series Device Ratings and Specifications table for part number
and brand information.

NOTE: Average power dissipation of transients not to exceed 0.25W, 0.4W, 0.6W or 1W for model sizes 7mm, 10mm, 14mm and 20mm, respectively.
Power Dissipation Ratings
100
Should transients occur in rapid succession, the average power dissipation
90
is the energy (watt-seconds) per pulse times the number of pulses per
second. The power so developed must be within the specifications shown
on the Device Ratings and Specifications table for the specific device.The
operating values of a MOV need to be derated at high temperatures as
shown in Figure 1. Because varistors only dissipate a relatively small
amount of average power they are not suitable for repetitive applications
that involve substantial amounts of average power dissipation.

NOTE: If pulse ratings are exceeded, a shift of V
N(DC)
(at specified current) of more than ±10% could result. This type of shift, which normally results in a decrease of V ,
N(DC)
may result in the device not meeting the original published specifications, but does not prevent the device from continuing to function, and to provide ample protection.

LA series varistors for Hi-Temperature operating conditions:
• Phenolic Coated LA Series devices are available with improved maxi-
mum operating maximum temperature 125°C.
• These devices also have improved temperature cycling performance
capability.
• To order this crimped and trimmed lead style, standard radial type
model numbers are changed by replacing the model letter “A” with “C”.
• Ratings and Specifications are as per standard LA Series except Hi-Pot
encapsulation Isolation Voltage Capability = 500V.
• To order: add X1347 to part number (e.g. V230LA20AX1347)
• Marked identifier will contain 'P' to denote Phenolic.
• These devices are not UL, CSA, VDE or CECC certified.
• Contact factory for further details.
Example:
For crimped leads without trimming and any variations to the above,
contact Littelfuse.
Ordering Information
LA series Varistors are shipped standard in bulk pack with straight leads
and lead spacing outlined in the package dimensions on page 4-13.
Contact your Littelfuse sales representative to discuss the non-standard
options outlined below.
• For 10/±1mm lead spacing on 20mm diameter models only; append
standard model numbers by adding “X10”.
Example:
For Lead-free and RoHS compliant parts add the letter ‘P’ after the base
part number and before any option as shown in the ordering example
below.
